How do i turn the cams to be in position? I mean i know the positions buy do i just use my hands to turn it or is there a tool, because the cams are kind of hard to turn...?
And what happens if i dont have enough bearing clearance and I start the motor anyway? (not that i would do that...)

 

Ok, so im gonna do a LS vtec and I bought some GSR ACL rod and main bearings, because they came in a pack. Now my question is will the GSR main bearings fit the LS block or do I have to get NON vtec main bearings???
